Article
The use of unconstrained lower limb exoskeletons has become a promising approach to assist individuals with gait impairments. The Honda Walking Assist (HWA) is a hip-assistive exoskeleton functioning as a gait trainer and has been shown to improve several gait related outcomes after training. Studies investigating its immediate effects on spatiotem...
Article
Background: Rehabilitation is important in the first months after a stroke for recovery of functional ability, but it is also challenging, since distinct recovery trajectories are seen. Therefore, studying the early changes in muscle characteristics over time (e.g. muscle strength, muscle mass and muscle volume), which are known to be associated w...
Article
BACKGROUND: Walking difficulties put an individual at high risk of falling, institutionalisation and even death. The use of robotical rehabilitation or assistive devices for walking has gained considerable interest as a means of improving patients’ gait abilities. OBJECTIVE: The aim of this research was to examine patients’ intrinsic motivation to...
Chapter
The present study investigated the level of perceived exertion during robot-assisted walking in non-ambulatory stroke survivors. In addition, we studied the relationship between the user’s subjective level of perceived exertion and objective measures of exertion (i.e. oxygen consumption and heart rate). Our results suggest that stroke survivors per...

This commentary is on the original article by Pool et al. on pages 328–335 of this issue.
Article
In stroke rehabilitation there is a growing body of evidence that not all patients have the same potential to recover. Understanding the processes that give rise to the heterogeneous treatment responses in stroke survivors will lay foundations for any conceivable advance in future rehabilitation interventions. This review was set out to shine new l...
Article
Introduction: Since there is no clear conclusion concerning the use of arm slings in the prevention or reduction of shoulder subluxation or shoulder pain in stroke patients, it seems important to explore other potentially beneficial effects. Earlier research already suggested that the upper limb might play a considerable role in efficient balance...
Article
This study aimed to investigate: 1) the effect of optic flow speed manipulation on active participation during robot-assisted treadmill walking (RATW), 2) the influence of the type of virtual environment, and 3) the level of motion sickness and enjoyment. Twenty-eight healthy older adults were randomized in two groups: “stimulus rich” Park group (5...
Article
Robot-assisted overground walking (RAOW) may facilitate walking aerobic exercise in nonambulatory stroke survivors. The aims of this study were to investigate the physiological responses and perceived exertion during RAOW in persons with stroke and to compare the exercise intensity to aerobic exercise guidelines for stroke survivors. Ten nonambulat...
Article
Purpose: To examine physiological responses and perceived exertion during robot-assisted treadmill walking in non-ambulatory stroke survivors; compare these outcomes with aerobic exercise recommendations; and investigate the effect of robotic assistance. Materials and methods: Twelve non-ambulatory stroke survivors (67 ± 11 years-old, 84 ± 38 d pos...
Article
Spatiotemporal gait analysis can provide quantitative information to assess treatment outcomes in stroke survivors. Therefore, clinicians need a portable, easy-to-use and low-cost tool, which accurately and reliably measures spatiotemporal gait parameters. This study examined the concurrent validity and reproducibility of the Gait Up© gait analysis...
Article
Background: During gait training in persons with central nervous system (CNS) movement disorders, virtual reality (VR) can offer added value by providing task-specific gait training in more interactive and motivating environments. Objective: To summarize current evidence for the effectiveness of VR-enhanced gait training in persons with CNS move...
Article
Purpose: To estimate pooled rates of gross and net energy consumption (ml/kg/min and J/kg/min) and energy cost (ml/kg/m and J/kg/m) during level surface walking with different assistance modalities post-stroke. Materials and Methods: Four databases were searched using keywords related to stroke, walking, and energy requirements. Three independent r...
Chapter
Robot-assisted gait rehabilitation improves gait- and balance related outcome measures, but its merit over other gait rehabilitation methods is still insufficiently proven. The trunk and pelvis are important to maintain balance during gait. Despite, scarce research has been presented concerning the importance of the trunk and the pelvis in differen...
Article
Introduction: Physiological responses are rarely considered during walking after stroke and if considered, only during a short period (3-6 minutes). The aims of this study were to examine physiological responses during 30-minute robot-assisted and body weight-supported treadmill and overground walking and compare intensities with exercise guidelin...
Article
Objective: The aim of this study was to collect patients' and healthcare professionals' opinions about lower limb orthoses (LL-orthoses): 1) the positive and negative aspects; 2) the differences in wearing them according to location; and 3) their recommendations for future modifications. Methods: Four focus group discussions were performed, with...
Article
Background and objective: Because user-satisfaction and acceptance may partly determine the grade of compliance to an orthotic device (OD), the aim of this multicentre observational study was to inquire the reasons for acceptance and the user-satisfaction of an OD of the lower limb in male and female central neurological movement disorders (CNMD)...
Article
Zusammenfassung Computergestütztes Gehtraining unterstützt Patienten dabei, die Gehfähigkeit wiederzuerlangen. Doch welche Feinheiten sich hinter dieser Aussage verbergen, beleuchtet der folgende Artikel.
Chapter
Energy consumption and cardiorespiratory load were assessed during 3 different walking conditions (Lokomat, treadmill and overground walking) in stroke patients. Preliminary results demonstrated that Lokomat walking was significantly less oxygen demanding than treadmill, but not overground walking. No significant differences in heart rate and minut...
Article
Objective: Show the benefit of kinematically compatible joint structures in exoskeletons for improving their performance in reducing metabolic consumption. Methods: Subjects were fitted with a hip exoskeleton, with misalignment compensation for all DOFs and were instructed to perform recurring sit-to-stand motions for 5 minutes. This was execute...

A shared design goal for most robotic lower limb exoskeletons is to reduce the metabolic cost of locomotion for the user. Despite this, only a limited amount of devices was able to actually reduce user metabolic consumption. Preservation of the natural motion kinematics was defined as an important requirement for a device to be metabolically benefi...
Article
Transcutaneous electric nerve stimulation (TENS) has proven to be effective for postsurgical pain relief. However, there is a lack of well-constructed clinical trials investigating the effect of TENS after total knee arthroplasty (TKA). In addition, previous investigations reported that low- and high-frequency TENSs produced analgesic tolerance aft...
Article
Background: In the development of efficacious driven gait orthoses (DGO), it is an added value to consider patients’ and therapists’ perspectives concerning robot-assisted gait training (RAGT). A better understanding of these issues may improve the process of care and outcome. Objectives: This study aimed to examine stroke patients’ motivation and...
Article
Purpose: The integration of sufficient cardiovascular stress into robot-assisted gait (RAG) training could combine the benefits of both RAG and aerobic training. The aim was to summarize literature data on the immediate effects of RAG compared to walking without robot-assistance on metabolic-, cardiorespiratory- and fatigue-related parameters. Meth...
Article
Introduction: Subjects with knee osteoarthritis walk differently compared to healthy subjects. Managing these gait alterations has been proven effective for reducing pain and increasing function. The Stride Analyzer is a low cost gait analysis tool but its clinimetric properties have not been investigated yet in subjects with symptomatic knee oste...
Article
Full-text available
Objective: To evaluate the clinical efficacy of transcutaneous electric nerve stimulation in the treatment of postoperative knee arthroplasty pain and to relate these results to the stimulation parameters used. Data sources: PubMed, Pedro and Web of Knowledge were systematically screened for studies investigating effects of transcutaneous electr...
